PITIVIAN.

SPECIFICATION forming part of Letters Patent No. 298,701, dated May 13,1884-.

' Application filed December 8, 1883. (No model.)

To all whom it may concern:

Be it known that we, LEBBEUS BALDWIN MILLER and PHILIP DIEHL, of thecity of Elizabeth, in the county of Union and State of New Jersey, havemade an invention of certain new and useful Improvements in Pitmen forSewing and other Machines; and I do hereby declare that the following isa full, clear, and exact description and specification of the same.

The object of this invention is to provide simple and reliable means-forconveniently placing such pitman in proper operative position by passingit over a crank-shaft or onto the pin or bend which forms the crank, andthereafter adjusting and taking up the wear of the hole or holes in suchpitman, through one of which the crank-pin or a portion of the crank tobe turned passes, and through the other of which passes the driving-pinof the usual reciprocal driver; and we accomplish this by regulating thesize of said hole or holes.

In the drawings, Figures 1 and 2 are front views of such pitman, andFigs. 8 and 4 are edge views, Fig. 3 being partly in section.

The pitman shown as embodying and illustrating our invention is of theform usually employed to receive reciprocating motion from the treadleof a sewing-machine and transmit motion to the rotary crank whichactuates the band or driving wheel of such machine. The

pitman A is formed with a recess or aperture, 13. Secured in saidpitman-head at the top of said recess is the internally-threaded nut C,

made preferably of iron. The screw D, provided with the pin-extension(2, passes loosely through a hollow in the pitman-head. Its

thread engages and operates in the nut D, and

its extension (1 enters and holds firmly the block E, which is adaptedto slide in the aperture B, and is moved by turning the screw D toregulate the extent of the aperture as desired, and held firmly by saidscrew and extension at the desired vertical point, being also heldfirmly against lateral motion by said extension.

WVe claim as our invention 1. In a pitman, the combination of anopening, a fixed nut formed separate from the pitman, a block adapted toslide in said opening,
